Beit known that l, WILLIAM EzRA Won- THEN, of the city, county, and State of New York, have made anew. and useful Invention of Hydraulic Connections for a Series of Wells or Cisterns 5v and that the following is a full, clear, and exact description and Aspecitlcation of the same. It frequently happens in practice that two or more wells or cisterne, or one :ormore wellsv cisterne, are

in connection'with one or more required to furnish a supply of water for one establishment; and the lobjects of this invention are to enable the several supplies of wa ter from di'e nt 4sources to be combined without the n cessity of sinking connectinglevels of the sources of supply of wateryalso, to dispense with thc'ne- Ycessity of operating-cocks or other means of regulating the supply from ,each source; and, further, to enable the quantity of water supf plied by the vseveral sources, to regulate the quantity drawn from each severally.

Tothis end my invention consists of certain combinations Y of suction-pipes with a siphompipe. and with a single pump suctionpipe, as are specified in detail at the close of this specification. In order that the said invention 'may be fully understood, I have represented in the accompanying drawings, and will proceed :to describe, the mode in which I have embodied my said invention in practical form.

This drawing gives as an example ,the ap plication' of the invention to a case in which a large or main open we1i,A, of the ordinary construction, is employed in connection with a smaller auxiliary open'well, B, and with a driven well, C, acting also as an auxiliary to the vmain welL A single pump, D, is in this case applied to draw water from the three Wells, and its suction-pipe E is in' this case applieddirectly to the main well A.

The two auxiliary wells B and (l are. each.

fitted with a separate suction-pipe, El andEz, and these auxiliary sucton-pipes are combined with the Siphon-pipe F, which extends into the main well A, with' which the l suction-pipe E ofthe pump' communicates. Y The siphon-pipe E is combined at its uppermost part with the pump suction-pipe E by tion with the suctionmeans of a small connection, G, and this con .nection G is by preference fitted with a checkf valve, e. The loweriend of the siphon-pipe F in the main well land the auxiliary suction-pipes El E, combined with the siphon-pipe F, extend downward in their'.

respective wells to the lowest level from which; water is to be drawn..

ln a combination of suction `and siplionf vpipes in wells, as above described, the opera tion of the pump exhausts directly the vmainf` suction-pipe leading intothe mainwell and.' also exhausts the 4siphon-pipe F. :an f the? auxiliary suctionpipes ll,1 4E3 throhgnthe' connection G. 0n the other,'l1 and,'when the pump is at rest and the siphon and auxiliary suctionpipes are free of air, the water from.' l the auxiliary wells B C will siphon over into the main well wheneverthe level of the water in the latter is. lowest, and the siphoning-will continue until the levels of water in th'e'wells will be equalized. The` water so siph'oned` is drawn from the main well through'the main suction-pipe E, so that the latter acts in :comj bination with the auxiliary' suction pipes and fsiphon-pipe to supply the pump Dwith water drawn originally `from the. auxiliary Y wells; and this isthe case even if the co'nnec` tion G be not used. lf'air shouldv getintdfthe siphon-pipe F when the connecticnfG'fis'femf A ployed, and should interrupt suchsiphqning before the levels are equalized, theiirst action of the pump .will remove such air through the connection, and consequently, whenever the action of the pump is stopped, the vsiplion-pipe and auxiliary suction-pipes are left freed of air and in the condition required' to transfer the water from the auxiliary wells tothe 'main well. lf the pump-pipe, pump, and its valves are tight, the check-valve 1n the connection G i' is not necessary; but in practice it is deemed advisable to use it as a precaution against the `return of air.

In place of connecting the highest 4part of f the siphon-pipe with the same pump D which 1s used to raise the water from the main Well, a

special pump or an ejector may be employed to free the siphon-pipe from air, the connecipe of the raising-pump being then unnecessary. l' l The advantages incident to this system are lower ends of the that one or more auxiliary wells situated at considerable distances from the main well ma be combined and utilized to furnish the sul;si ply drawn by a-puinp, `and. yet the con'ne'e! tions between the -variou's wells may be 'practically about twenty-live 'feet above the lowest level otlthe water in the auxiliary wells, thus avoiding the necessity and. expense of sink` ing the connecting-pipes downto the lowest level from which wateris to be drawn from the auxiliary wells. The connection of the `suction-pipes of auxiliary wells with a mainy well by means of a Siphon-pipe also` permits the water to be drawn slowly from the auxil iary wells, so that a sudden rush of water into them and the consequent disturbance of thel ,earth surrounding the bottom of the Well are l i avoided, because the' suction-pipe of each aux:

iliary well may be made of such small size as to pass the water slowly, while the quantity of water accumulated inthe main well will be sufficient to supply the pump rapidly when it is worked. `1f sand should, however, be drawn same pump which is used to draw water from the main well, thus dispensing with the neeessity of using aspecia -pump or other device' to exhaust thesiphoipipe. l

Although I'have described the invention as i appliedfto combine wells, itis obvious that it may be applied to combine two or more cis terns forfh'olding water (such cisterns taking the places of the wells) or to combine a cistern and a well. l i

-I claim as my combination- 1. The combination of several wells .by

means of a suction-pipe in each auxiliary well. and a siphon-pipe in the main well combined, substantially as before set forth.

2. The combination, substantially as'before 'set' forth, of the main and auxiliary wells with a a single pump by means of the suction-pipe ofthe main well, a suction-pipe -for each auxiliary well, and the Siphon-pipe delivering into' the main Well. i

3. The combination substantially' as bfre set forth, of the suction-pipe of a main well,l A

theauxiliary suction-pipe, the lsi honi-pipe',

and the connection between the mam suction pipe and the Siphon-pipe.
